Nomenclature transuranium elements

The transuranium elements are the elements following uranium in the periodic table. The elements from rutherfordium (Rf, Z = 104) through meitnerium (Mt, Z = 109) were formally named in 1997. The transmeitnerium elements, the elements beyond meitnerium (including hypothetical nuclides that have not yet been made), are named systematically, at least until they have been identified and there is international agreement on a permanent name. The systematic nomenclature uses the terms in Table 17.2. For example, the element with Z = 111, one atom of which was first made in 1994, will be called unununium, Uuu, until it is finally named. 

As had always been the rule in element discovery the discoverer proposed a name for the new element. As one element often was synthesized in two or even three of the big research institutes an inflamed debate arose regarding some of the elements. The Commission of Nomenclature of Inorganic Chemistry (CNIC) proposed a name list in 1994 but the controversies remained. The International Union of Pure and Applied Chemistry (lUPAC) interviewed chemists round the world regarding the naming and has, since 1997, decided about official names for the transuranium elements.
